We got a few decent photos from ours, but many more where they were triggered too late to see what it was that been there. They're definitely not the best cameras in the world. Haven't had the split screen issue with ours though!
TT, I'm guessing that you have a previous model AldiCAM. Your photos are dated from before 19th June 2014 which was when the MK3 was released, and the info. displayed at the bottom of the picture looks different.
Also the current model doesn't click on and off the battery pack, it is permanently attached by a hinge, and the back also has to be opened to remove the SD card.
It is a pretty hopeless design because you either have to review photos in-situ, (crouched by tree trunk or wobbling about on ladder etc.) or remove your mounting straps etc. and then faff about to strap it back up again afterwards.
Best as you say to swap SD cards and fresh batteries, then review later on PC, camera etc.
I use an Android tablet, with OTG cable and SD card reader.
I think you are describing the previous version which was a copy of the Ltl Acorn, with a bottom hatch to change the batteries or SD card without disturbing the mounting. A much better design IMHO and much less chance of water ingress due to leaks, or simply having to open the back in wet conditions.
Current Aldi model is totally reliant on the gasket sealing properly. Ltl design will probably be ok even if gasket leaks, as hatch is at lowest part of body. On current Aldi model all the cells are in the back part. On the Ltl design the first 4 batteries are inside the main body and removable through the bottom hatch, along with the SD card.
If you don't need all 8 cells, I suggest stuffing silica gel sachets into empty compartment to ensure camera stays bone dry and fog proof.
